nonsturgeon
Nonsturgeon is an informal term used in fisheries biology and ecology to refer to organisms that are not sturgeon, i.e., not members of the family Acipenseridae. The term is not a formal taxonomic category; rather, it serves as a broad, descriptive label used in field data and landing records to separate sturgeon catches from all other species in mixed fisheries or survey catches.
Practically, "nonsturgeon" can include a wide range of taxa, such as salmon, carp, catfish, and various invertebrates
Because the category is non-specific, analyses that rely on it can obscure differences among non-sturgeon species
Origin and regional usage vary. The term emerges from the need to distinguish sturgeon in surveys and
